Forsythia is used for swelling of small air passages in the lung (bronchiolitis), tonsillitis, sore throat, fever, vomiting, heart disease, HIV/AIDS, gonorrhea, pain and swelling (inflammation), and a severe skin rash with fever and vomiting caused by a bacterium (erysipelas).
Sometimes forsythia is given intravenously (by IV) in combination with other herbs for treating bronchiolitis.
Insufficient Evidence to Rate Effectiveness for...
- Inflammation of small air passages in the lung (bronchiolitis). Developing research suggests that children with bronchiolitis due to a particular infection (respiratory syncytial virus infection) get over their symptoms faster when given a combination of forsythia, honeysuckle, and Baikal skullcap intravenously (by IV).
- Sore throat.
- Pain and swelling (inflammation).
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).

Special Precautions & Warnings:Pregnancy and breast-feeding: Not enough is known about the use of forsythia during pregnancy and breast-feeding. Stay on the safe side and avoid use.

Interaction Rating: Moderate Be cautious with this combination.
Talk with your health provider.
Forsythia might slow blood clotting. Taking forsythia along with medications that also slow clotting might increase the chances of bruising and bleeding.
Some medications that slow blood clotting include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.
